Default Notebook Extensions for Better Presentations:

Present working directory path

from sklearn import datasets
import pandas as pd
wine_data = pd.DataFrame(datasets.load_wine().data)
wine_data.columns = datasets.load_wine().feature_names
wine_data.head(5)

Accessing/loading a files

If File is available in the same current working directory folder

import pandas as pd

df1 = pd.read_csv(
    'hcpuniverse.csv', sep=";"
)  #goback to the previous parent directory files other than present working directory

df1.shape

(3681, 6)



(3681, 6)

If the File is available in the folder curresponding the same working directory location

import pandas as pd

df2 = pd.read_csv(
    '01A-data/hcpuniverse.csv', sep=";"
)  #goback to the previous parent directory files other than present working directory

df2.shape

(3681, 6)



(3681, 6)

OR

import pandas as pd

df3 = pd.read_csv(
    './01A-data/hcpuniverse.csv', sep=";"
)  #goback to the previous parent directory files other than present working directory

df3.shape

(3681, 6)



(3681, 6)

Accessing/loading a file which present in other than current/present working directory exact parent of current

import pandas as pd

df4 = pd.read_csv(
    '../01-data/hcpuniverse.csv', sep=";"
)  #goback to the previous parent directory files other than present working directory

df4.shape

(3681, 6)



(3681, 6)

df4.head()

Accessing/loading a file which present in other than current/present working directory grand parent of current path

import pandas as pd
df5 = pd.read_csv('../../00-Python/hcpuniverse.csv',sep=";") #goback to the previous/parent directory files

df5.head()

import pandas as pd
df6 = pd.read_csv('../../../DSAIML/hcpuniverse.csv',sep=";") #goback to the previous/parent directory files

df6.head()

Accessing/loading a file which present in other than current/present working directory other than grand parent of current path, super path let’s say computer account name path

import pandas as pd

df7 = pd.read_csv(
    '~/hcpuniverse.csv', sep=";"
)  #goback to the computer's account named directory(if the file located there) "C:\Users\Administrator" is nothing but ~

df7.head()

Embedding Images From Online and Local Folder

Embedding Images From Local Folder:

Above Code we can Use This Below Code as per Obsidian Point of view to display in the Obsidian platform:
![[imgsAudVid/Engelbart.jpg]]

Using Python Code

from IPython.display import Image
i = Image(filename='../03-imgs/1_N1tiuQF9phkp8eYlum9twA.jpeg')
i # list of things you can pass to a dataframe

Download Notebook as PDF, markdown, html and others:

Note: To get above please go through below document to install sufficient software tools:`

nbconvert: Convert Notebooks to other formats:https://nbconvert.readthedocs.io/en/latest/index.html

First Approach

Source: https://mpievolbio-scicomp.pages.gwdg.de/blog/post/2020-12-09_pandoc_vs_nbconvert/
pandoc --to pdf --from ipynb -o Notebook.pdf Notebook.ipynb
OR
Download as PDF via LaTex(.pdf)
OR
Goto Chrome three dots choose print option and Save as PDF

Second Approach

Use Another Approach like below:
